Setup v4 releases (#15961)

Now that Tailwind CSS v4 is released, we can setup a proper release
workflow again. This setup mimics the workflow of how we did it in v3,
but adjusted to make it work on the v4 codebase.

Whenever a PR is merged into the `next` branch, we will publish an
insiders release to npm using the following version number:
`0.0.0-insiders.<commit-hash>`. Note: insiders releases will not have a
GitHub release associated with them, therefore the `standalone-cli`
won't be available as an insiders release.

For the normal release procedure, the following steps are required:

1. Manually version the packages (e.g.: `pnpm run version-packages`)
2. Create a git tag for the version you want to release
3. Push the updated package.json files and the git tag to the repository

Next, a GitHub action will kick in once a `tag` is being pushed.

The GitHub action will run a build, and create a draft release on GitHub
that will contain:

1. The CHANGELOG.md contents for the last version
2. The `standalone-cli` artifacts attached to the drafted release

Once you are happy with the draft, you can publish the draft on GitHub.

This in turn will trigger another GitHub action that will publish the
packages to npm.

Whenever an insiders release or a normal release completes, we will also
trigger Tailwind Play, to update its dependencies to the latest version
of Tailwind CSS.

---

Note: some of the GitHub Action workflows still refer to the `next`
branch instead of the `main` branch. If we later today want to get a new
release out, we can merge `next` into `main` and update the workflows
accordingly.


---

This is hard to test, but I started from the existing release.yml file
and adjusted things accordingly. The biggest change is related to the
insiders version. If you look at this temporary
[commit](572dddfc33),
you can see that the publishing (dry-run) seems to work as expected:
